LGJ2D331MELC15 Equivalent & Substitute Parts

Part Overview

The LGJ2D331MELC15 is a 330 µF, 200 V aluminum electrolytic capacitor manufactured by Nichicon in the LGJ series. This radial, can-style snap-in capacitor is rated for 2000 hours at 105°C and is designed for general-purpose applications requiring through-hole mounting. The part is active and ROHS3 compliant.

Substitute parts are necessary when the original LGJ2D331MELC15 becomes unavailable due to inventory constraints, manufacturing discontinuation, or supply chain disruptions. Alternative models with equivalent electrical specifications and compatible mechanical dimensions ensure design continuity and system reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LGJ2D331MELC15 is determined by the following criteria:

Mandatory Matching Parameters:

• Capacitance: 330 µF
• Voltage Rating: 200 V
• Tolerance: ±20%
• Polarization: Polar
• Lead Spacing: 10.00 mm
• Package Type: Radial, Can - Snap-In
• Mounting Type: Through Hole

Allowable Variations:

• Lifetime @ 105°C: Substitute parts may exceed 2000 hours (higher lifetime is acceptable)
• Physical Dimensions (Diameter and Height): Variations permitted within mechanical envelope constraints
• Ripple Current Ratings: Variations permitted based on series design
• Manufacturer: Different manufacturers acceptable if all mandatory parameters match

All substitute parts listed meet these criteria and are confirmed as direct functional equivalents for the LGJ2D331MELC15.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component deployment.

Nichicon LGN Series (LGN2D331MELY30, LGN2D331MELZ25): These parts offer extended lifetime ratings of 3000 hours at 105°C compared to the original 2000-hour specification. Both maintain identical electrical parameters and lead spacing. Physical dimensions vary, with LGN2D331MELY30 featuring a smaller diameter (20.00 mm) but greater height (32.00 mm), and LGN2D331MELZ25 providing a mid-range profile (22.00 mm diameter, 27.00 mm height).

Nichicon LGW Series (LGW2D331MELZ25): This substitute provides enhanced ripple current handling (1.97 A @ 120 Hz, 2.955 A @ 50 kHz) with a 3000-hour lifetime rating. Physical dimensions are comparable to LGN2D331MELZ25 (22.00 mm diameter, 25.00 mm height).

Cornell Dubilier Electronics 381LX Series (381LX331M200J012): This cross-manufacturer substitute delivers equivalent electrical specifications with 3000-hour lifetime. Moisture sensitivity level is rated at 1 (Unlimited). Physical dimensions are 25.00 mm diameter and 27.00 mm height.

Selection should prioritize mechanical fit within the PCB layout constraints, as diameter and height variations are the primary differentiators among functionally equivalent alternatives.

Frequently Asked Questions (FAQ)

Q: Can LGN2D331MELY30 directly replace LGJ2D331MELC15 on the PCB?

A: Electrical substitution is valid. However, the LGN2D331MELY30 has a smaller diameter (20.00 mm vs. 35.00 mm) but greater height (32.00 mm vs. 17.00 mm). PCB layout verification is required to confirm mechanical clearance in the mounting area.

Q: What is the primary difference between LGN2D331MELZ25 and LGW2D331MELZ25?

A: Both are 330 µF, 200 V snap-in capacitors with 3000-hour lifetimes and identical lead spacing. The LGW series offers higher ripple current ratings (1.97 A @ 120 Hz vs. 1.2 A). Physical dimensions are similar (22.00 mm diameter), with LGW2D331MELZ25 being slightly shorter (25.00 mm vs. 27.00 mm height).

Q: Is the 381LX331M200J012 from Cornell Dubilier a suitable substitute?

A: Yes. It meets all mandatory electrical parameters (330 µF, 200 V, ±20% tolerance, 10.00 mm lead spacing) and is ROHS3 compliant. Physical dimensions are 25.00 mm diameter and 27.00 mm height. Verify PCB layout compatibility before deployment.

Q: Why do substitute parts have longer lifetimes (3000 hours vs. 2000 hours)?

A: Extended lifetime ratings represent improved design or material specifications in newer series. A longer-rated part is functionally compatible and provides equal or superior performance in the original application.

Q: Are all substitute parts through-hole mounted with snap-in packaging?

A: Yes. All listed substitutes are radial, can-style snap-in capacitors with through-hole mounting and 10.00 mm lead spacing, ensuring compatibility with standard PCB footprints designed for the LGJ2D331MELC15.

Q: What should I verify before selecting a substitute?

A: Confirm PCB layout clearance for the substitute's physical dimensions (diameter and height). Verify that the mounting footprint accommodates the 10.00 mm lead spacing. All electrical and compliance parameters are equivalent across all listed substitutes.
